8-5 Sorting

One of the most common applications in computer One of the most common applications in computer science is sorting—the process through which data are science is sorting—the process through which data are arranged according to their values. We are arranged according to their values. We are surrounded by data. If the data are not ordered, we surrounded by data. If the data are not ordered, we would spend hours trying to find a single piece of would spend hours trying to find a single piece of information. information.
